Cleaning and replacing the air filter
If the air filter becomes clogged with dust, the internal temperature of\
 the
projector will rise, the TEMP indicator will flash and the projector pow\
er will
turn off. The air filter should be cleaned every 100 hours of use,
depending on the location where the projector is being used.
Cleaning procedure
# Turn off the MAIN POWER
switch and disconnect the
power cord plug from the
mains socket.
Turn off the MAIN POWER switch
according to the procedure given
in “Turning off the power ” on
page  31 before disconnecting the
plug from the mains socket.
$ Gently turn the projector
upside down.
NOTE:
B Place the projector on top of a
soft cloth so that it will not
become scratched.
% Remove the air filter.
Put your fingernails under the air
filter and pull the air filter out of
the projector. &
Clean the air filter.
Use a vacuum cleaner to clean
off any accumulated dust.
NOTE:
B Be careful not to let the air filter
get sucked into the vacuum
cleaner.
' Install the air filter.
NOTE:
B Be sure to install the air filter
cover before using the projector.
If the projector is used without the
air filter cover installed, dust and
other foreign particles will be
drawn into the projector, and
malfunctions will result.
B If the dust cannot be removed by
cleaning, it is time to replace the
air filter. Please consult your
dealer. Furthermore, if the lamp
unit is being replaced, replace the
air filter at this time also.

Replacing the lamp unit
Warning
When replacing the lamp, allow it
to cool for at least one hour
before handling it.
BThe lamp cover gets very hot,
and contact with it can cause
burns.
Notes on replacing the
lamp unit
BThe light generating lamp is
made of glass, so dropping it or
allowing it to hit hard objects may
cause it to burst. Be careful when
handling the lamp.
BAfter having removed the old
lamp, carelessly discarding it can
cause the lamp to burst. Dispose
of the lamp with the same care
that would be taken with a
fluorescent light.
BA Phillips screwdriver is
necessary for removing the lamp
unit. Make sure that your hands
are not slippery when using the
screwdriver.
NOTE:
BThe projector is not supplied with
a replacement lamp unit. Please
ask your dealer for details. Lamp
unit product no.: ET-LA780
CAUTION:
BDo not use any lamp unit other
than the one with the product
number indicated above.
Lamp unit replacement
period
The lamp is a consumable product.
Even when the full life of the bulb
has not been exhausted, the
brightness of the light will gradually
decline. Therefore periodic
replacement of the lamp is
necessary.
The intended lamp replacement
interval is 1 500 hours, but it is
possible that the lamp may need to
be replaced earlier due to variables
such as a particular lamps
characteristics, usage conditions
and the installation environment.
Early preparation for lamp
replacement is encouraged.
A lamp that has exceeded 1 500
hours of use has a much greater
chance of exploding. In order to
prevent the lamp from exploding,
the lamp will be automatically shut
off when 1 500 hours of use have
been reached.
NOTE:
BThe usage hours explained
above are for use when the HIGH
setting has been selected for
LAMP POWER in the OPTION
menu. If the LOW setting is
selected, the brightness of the
lamp will be less and life of the
lamp can be extended.
BWhile 1 500 hours is the intended
replacement interval, it is not a
period of time covered by
warranty.
